The proportions I prefer, expressed approximately, are, lead, seven hundred and ninety five parts antimony, one hundred and fifty-five parts; tin, forty-seven and one-half parts, and cadmium two and one-half parts. I of course do not restrict myself to the proportions mentioned, as variations may be and are made according to the use for which the alloy is designed.

In making my alloy the lead and antimony are melted together and thoroughly stirred 2. An alloy in which are combined lead, an-

timony, tin and cadmium.

3. An alloy in which are combined lead, between five hundred and eight hundred parts; antimony, between one hundred and one hundred and sixty parts; tin, between twentyfive and fifty parts; and cadmium, between one and sixteen parts.
